options

The possible options are:

  • FT_UID - The msgno argument is a UID
  • FT_INTERNAL - The return string is in "internal" format, without any attempt to canonicalize to CRLF newlines
  • FT_PREFETCHTEXT - The RFC822.TEXT should be pre-fetched at the same time. This avoids an extra RTT on an IMAP connection if a full message text is desired (e.g. in a "save to local file" operation)
